Answer:

Step-by-step explanation:
Use the <u>Slope Formula</u> to determine the slope of two given points:

First Point: 
Second Point: 
-Substitute both points:
First Point: 
Second Point: 

-Solve for the slope:



Therefore, the slope is 
Answer:
A sample size of 345 is needed so that the confidence interval will have a margin of error of 0.07
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error of the interval is given by:

In this problem, we have that:

99.5% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.07?
This is n when M = 0.07. So







A sample size of 345 is needed so that the confidence interval will have a margin of error of 0.07

n=-2
Answer:
Option 4 : 
Step-by-step explanation:
<u>See the attached figure:</u>
To find the vertices of the feasible region, we need to graph the constraints, then find the area included by them, then calculate the vertices which is the intersection between each two of them.
As shown, the shaded area represents the solution of the constraints
So, the vertices of the feasible region are:

Answer:
b. 13
Step-by-step explanation:
163-9=154 to get the amount of people coming
154÷12=12.833 is the amount of tables needed if each seat 12 and 154 people are coming
round up to 13 because you cant have 12.833 tables
